I regret not buying the Nakamichi NEP-MV10 dual-driver in ear monitors with three-button controland mic when I was at Changi duty-free. They sounded very good for the price and works perfectly well with my HTC 8S (not on iPhone 5S and may require an adapter for Nokia).

Jays Five have mediocre reviews.
Why the hell couldn't they mass market that Nokia Purity cable. Could have used almost any headphone available in the market today with a detachable cable.
I actually think they would sell like hotcakes
